[Osteosynthesis with cervico-diaphyseal penetration in the treatment of complex pertrochanteric fractures. Apropos of a continuous series of 180 cases].

180 comminuted fractures of the trochanteric region in elderly patients were fixed by nail-plates with some degree of upward displacement of the shaft and impaction. 81 p. 100 of the patients were allowed to bear full weight soon after the operation. Severe secondary displacement was observed in only 2.7 p. 100. This technique makes nursing easier and hospitalisation shorter. Some details of the mechanical basis and the technique of operation are given.
